本机适用于橡胶软管外胶层耐磨耗性的测定。将试样套于芯轴上，然后用一磨具在规定荷重及行程下在试样表层来回磨擦，检测试样的外胶层耐磨耗性。 This machine is designed to determine the resistance of rubber hose outer cover to abrasion.The test involves mounting the specimen on a mandrel, and then using an abrasive tool to repeatedly rub the surface of the specimen under a specified load and stroke to evaluate the wear resistance of the outer rubber layer.
